Definitions
- the present invention relates generally to computer systems.
- the present invention relates to computer systems that share resources such as storage.
- Servers are typically used for big applications and workloads such as those used in conjunction with large web services and manufacturing. Often, a single server does not have enough power to perform the required application. To accommodate these large applications, several servers may be used in conjunction with several shared storage devices in a storage area network (SAN). In addition, it may be valuable to group servers together to achieve better availability or manageability.
- SAN storage area network
- Fig. 1 is a block diagram of a shared storage system suitable for facilitating an embodiment of the present invention.
- Figs. 2A-2C are examples of journal entries according to an embodiment of the present invention.
- Fig. 3 is a flow diagram of a method for journal recovery according to an embodiment of the present invention.
- Figs. 4A-4B are flow diagrams of a method for analyzing the journal, such as step 304 of Fig. 3, according to an embodiment of the present invention.
- Figs. 5 A-5B are flow diagrams of a method for replaying selected transactions during journal recovery according to an embodiment of the present invention.

- Figs. 7A-7C are flow diagrams of a method for replaying the selected transactions for journal recovery according to ,the alternate embodiment of the present invention.
- Fig. 1 is a block diagram of a shared storage system suitable for facilitating an embodiment of the present invention.
- nodes 102A-102D are coupled together through a network switch 100.
- the network switch 100 can represent any network infrastructure such as an Ethernet, InfiniBand network or Fibre Channel network capable of host-to-host communication.
- the nodes 102A-102D are also shown to be coupled to a data storage interconnect 104.
- An example of the data storage interconnect 104 is a Fibre Channel switch, such as a Brocade 3200 Fibre Channel switch.
- the data storage network might be an iSCSI or other LP storage network, InfiniBand network, or another kind of host-to-storage network.
- the network switch 100 and the data storage interconnect 104 may be embodied in a single interconnect.
- nodes 102A-102D include but are not limited to computers, servers, and any other processing units or applications that can share storage or data.
- nodes 102A-102D will sometimes be referred to as servers.
- the data interconnect 104 is shown to be coupled to shared storage 106A-106D.
- shared storage 106A-106D include any form of storage such as hard drive disks, compact disks, tape, and random access memory.
- Shared storage can be any storage device, such as hard drive disks, compact disks, tape, and random access memory.
- a filesystem is a logical entity built on the shared storage. Although the shared storage is typically considered a physical device while the filesystem is typically considered a logical structure overlaid on part of the storage, the filesystem is sometimes referred to herein as shared storage for simplicity. For example, when it is stated that shared storage fails, it can be a failure of a part of a filesystem, one or more filesystems, or the physical storage device on which the filesystem is overlaid. Accordingly, shared storage, as used herein, can mean the physical storage device, a portion of a filesystem, a filesystem, filesystems, or any combination thereof.
- Figs. 2A-2C are examples of journal entries according to an embodiment of the present invention.
- a journaling mechanism is used to allow multiple independent processing nodes to update a common set of data structures atomically, even if these updates affect multiple blocks and the hardware is not capable of updating multiple blocks atomically.
- a journal records information about updates, possibly affecting multiple blocks, in a way that is easily located following a system failure. The act of creating a set of such updates that preferably occurs atomically is called a transaction. Each transaction is recorded in the journal with a journal entry.
- a journal entry includes a set of blocks written into the journal; these blocks include copies of the block values to be written as part of the update, along with information specifying the locations where these new values will be written. Sometimes these locations will be referred to as the final locations for the update, distinguished from the copies of the block values in the journal entry itself.
- journal entry When all new values in a particular journal entry have been written to their final locations, the journal entry can be marked expired. An expired journal entry need not be retained, since all the updates it records have been performed; the space it takes up can be re-used for another purpose.
- node 3 retains information in its local memory, ready to update block B to 3,000 and block C to 1,500.
- each blocks is assumed to store just an integer, and blocks are named by letters.
- blocks B and C may represent two separate bank accounts wherein the user has transferred money from bank account B to bank account C.
- Node 3 has the information but has not yet recorded it in the journal.
- Node 1 has set block X to 750, set block Y to 1250 and the journal entry recording this transaction has been made valid.
- Node 7 has set block Q to 50. Note that node 7 is in the middle of writing the transaction and the journal entry is not yet valid.
- Node 4 retains information in memory and wants to update block A to 500.
- node 4 wants to update block B as part of the same transaction updating block A to 500.
- Block B is part of a transaction from node 3 that is not yet valid (as shown in Fig. 2A). Accordingly, node 4 asks node 3 to make that transaction valid in order for node 4 to update block B.
- node 3 completed writing a journal entry recording the update that sets block B to 3000 and, block C to 1500, and the transaction is now valid.
- node 3 has completed writing a journal entry for a prior transaction which set block C to 1000 and block D to 250.
- Node 7's journal entry is still not yet valid since it has not yet finished writing out its transaction.
- Node 4's journal entry remains empty.
- node 4 can write a journal entry for its transaction now that node 3 has finished its transaction with regard to block B. Note that valid journal entries do not have to be contiguous according to an embodiment of the present invention. At time 3, nodes 3, 1, and 4 have written valid transactions while node 7's transaction still remains not valid.
- Fig. 3 is a flow diagram of a method for journal recovery according to an embodiment of the present invention.
- a failure is detected (300).
- Examples of failures can include a server failure during a journal update.
- grants of new locks are paused (302).
- a shared resource environment such as a storage area network
- locks are often used to ensure that all the nodes accessing a block of data will access the latest version.
- the granting of new locks are paused.
- the journal is analyzed (304), then selected transactions are replayed (306), then ordinary operations are continued (308).
- Figs. 4A-4B are flow diagrams of a method for analyzing the journal, such as step 304 of Fig. 3, according to an embodiment of the present invention.
- Figs. 5A-5B are flow diagrams of a method for replaying selected transactions during journal recovery, such as step 306 of Fig. 3, according to an embodiment of the present invention.
- Figs. 4A-4B and 5 A-5B are preferably read in conjunction.
- Metadata blocks include but are not limited to data structure information such as file name, date a file was opened, length of file, and where contents of a file is stored.
- a given block may at one time belong to the set of metadata blocks, and later belong to the set of non-metadata blocks, or vice- versa; changes of blocks from one category to the other are recorded in journal entries in the journal.
- the journal recovery mechanism selectively updates only the appropriate blocks according to the metadata/non-metadata distinction.
- a list of blocks is set to null (400). This list will record blocks which are not metadata blocks.
- the oldest unexpired transaction is retrieved (402). It is determined whether the transaction contains a change of metadata/non-metadata block status (404). This determination looks to see whether the journal entry for this transaction records a block or blocks changing from belonging to the set of metadata blocks to the set of non-metadata blocks or vice- versa. This type of change is preferably recorded in the transaction and can be determined by reading the transaction. If the transaction does contain a record of changing metadata/non-metadata block status (404), then the first record of a block changing its metadata/non-metadata status is retrieved (406). There is preferably a record in the journal entry that indicates whether this particular block is or is not metadata, and it is this record that is retrieved.
- the analysis of the journal results in a list of non-metadata blocks to ensure that the non-metadata blocks are not tampered with in the journal recovery. This method of analyzing the journal allows the set of metadata blocks to change dynamically.
- Figs. 5A-5B are flow diagrams of a method for replaying selected transactions during journal recovery according to an embodiment of the present invention.
- Figs. 5A-5B show an example of step 306 of Fig. 3 and is preferably read in conjunction with Figs. 4A-4B.
- a particular node retrieves the oldest unexpired valid transaction (500). The first block in the transaction is retrieved (502). It is then determined whether this block is in the list of non-metadata blocks (504). The list of non-metadata blocks was established in the analysis of the journal in step 304 of Fig. 3 and Figs. 4A-4B.
- this block is not in the list of non-metadata blocks (504), then it is determined if this block is covered by a lock which is held by a surviving node (506).
- a surviving node is a node that has not failed. If the block is not covered by a lock held by a surviving node then this node writes the block to its final location (508).
- this block is in the list of non-metadata blocks (504 of Fig. 5A), or if this block is covered by a lock held by a surviving node (506 of Fig. 5A), then it is determined if there are more blocks in the transaction (510). If there are more blocks, then the next block is retrieved (516), and then it is determined if this new block is in the list of non-metadata blocks (504 Fig. 5A).
- the transaction is marked as expired (512). It is then determined whether there are more valid expired transactions (514). If there are more unexpired valid transactions then the next unexpired valid transaction is retrieved (518), and the first block of the transaction is retrieved (502 Fig. 5A). If there are no more unexpired valid transactions (514), then the journal recovery is complete.
- Figs. 6A-6B are flow diagrams for a method for analyzing the journal according to an alternate embodiment of the present invention.
- Figs. 6A-6B are further details of the step of analyzing the journal (304 of Fig. 3) and should be read in conjunction with Figs. 7A-7C, which are further details of the step of replaying selected transactions (306 of Fig. 3).
- the journal recovery is selective for a failed node's updates but does not account for blocks changing from metadata to non-metadata status or vice versa.
- a list of blocks is set to null (600). When this analysis is finished, this list will consist of blocks last updated by a failed node. The oldest, unexpired valid transaction is retrieved (602). It is then determined if this transaction is from a failed node (604). If it is not from a failed node then the first block in the transaction is retrieved (606). The block is then removed from the list if it is present on the list (608). The list is the one that was established in step 600. Since a particular block may have been involved in several transactions the block may be listed on the list due to a first transaction, then later removed from the list due to a second transaction.
- this transaction is from a failed node (604), then the first block in the transaction is retrieved (618 of Fig. 6B). This block is then added to the list (620), and then it is determined if there are more blocks in the transaction (622). If there are more blocks, then the next block transaction is retrieved (624), and this new block is added to the list (620). If there are no more blocks in the transaction then it is determined if there are more valid transactions in the journal (614 of Fig. 6A).
- Figs. 7 A-7C are flow diagrams of a method for replaying the selected transactions for journal recovery according to the alternate embodiment of the present invention. This method is the alternate embodiment of step 306 of Fig. 3 and should be viewed in conjunction with Figs. 6A-6B.
- the oldest unexpired valid transaction is retrieved (700). It is then determined if this transaction is from a failed node (702). If it is not from a failed node, it is determined if there are more unexpired valid transactions (704). If there are more transactions, then the next unexpired valid transaction is retrieved (706). If there are no more unexpired valid transactions (704), then the journal recovery is finished.
- the transaction is from a failed node (702), then the first block in the transaction is retrieved (710). It is then determined if the block is in the list of blocks most recently updated by a failed node (712). This list is the same list that was derived in the method shown in Figs. 6A-6B. If the block is on the list, then it is determined whether the block is covered by a lock held by a surviving node (714). A surviving node is a node that has not failed. If the block is not covered by a lock held by a surviving node, then the block is written to its final location (716). It is then determined if more blocks are in the transaction (720).
- This determination is also made if the block is not on the list of blocks most recently update by a failed node (712 of Fig. 7B), or the block is covered by a lock held by a surviving node (714 of Fig. 7B). If there are no more blocks in the transaction (712), then it is determined if there are more unexpired valid transactions (704 of Fig. 7A). If, however, there are more blocks in the transaction (720), then the next block is retrieved (722), and it is determined if the new block is in the list of blocks most recently updated by a failed node (712 of Fig. 7B).
